#### Abstract

We answer some questions raised in [1]. In particular, we prove: (i) Let *F* be a compact subset of the euclidean plane *E ^{2}* such that no component of

*F*separates

*E*

^{2}. Then

*E*can be partitioned into simple closed curves iff F is nonempty and connected. (ii) Let

^{2}\F*F Ç E*

^{2}be any subset which is not dense in

*E*, and let

^{2}*S*be a partition of

*E*into simple closed curves. Then

^{2}\F*S*has the cardinality of the continuum. We also discuss an application of (i) above to the existence of flows in the plane.
